Abstract

In an animation encoding method, an animation decoding method, an animation recording medium and an animation encoder, the present invention suppresses the reduction of information having a fine image pattern while reducing a mosquito noise even in a signal band in which an S/N ratio is low. An animation signal is encoded by using a predetermined anticipation image signal, applying a predetermined operation to the signal so encoded, quantizing the signal obtained by the operation and the signal so quantized is subjected to variable length encoding. In this instance, the signal band in which the S/N ratio of the image signal drops is quantized and highlighted on the basis of non-linear characteristics. On the decoding side, on the other hand, decoded signals are reversely quantized on the basis of non-linear characteristics having opposite characteristics to the encoding side, and decoding is effected. <IMAGE>
